CVE-2011-1839

Estado: ModificadaMedia (5)—

IBM Rational Build Forge 7.1.0 uses the HTTP GET method during redirection from the authentication servlet to a PHP script, which makes it easier for context-dependent attackers to discover session IDs by reading (1) web-server access logs, (2) web-server Referer logs, or (3) the browser history.
